I want to a single zone radiant floor system in order to heat the ceramic floor of my family room. My plan was to use the existing water heater since I'm only doing a single zone that measures roughly
15 x 15. So with that said could you kindly critique my plan. Please follow the link.- attach a tee or 2 zone manifold. One for Hot feed to house and one for radiant zone.
- On run to radiant zone install cutoff valve before the circulation pump.
- Install circulation pump. Question here, can I use a zone valve instead?
- Run my return line to another 2 zone manifold running into the hot water heater
- At the radiant zone return install another shut off valve.
- Run my PEX allowing for double lines in between each floor joist.
- Question: Based on my room dimensions I believe I'm going to be reaching the limit for the length of recommended PEX? Room is 15 x 15 and based on double runs roughtly of 13' (26') per joists x 11 (spaced
- How would I best handle the above situation? 2 runs/zones for this one room? Will this be to much for my gas water heater?
- Attach PEX to subfloor using staples.
- Use aluminum heat transfer plates. Do I need to cover the entire run of PEX? Can I use aluminum flashing?
- Insulate and not allow but for maybe 2" of air space.
So, critique away!!
thanks
